Best outbound sales agencies for B2B SaaS

The ten at a glance

Read the middle column first. These ten are not selling the same thing, and for SaaS the difference between renting headcount and buying meetings is the whole decision.

Everything in that table was read on the company's own site or its Clutch profile between 8 and 12 November 2026. "Not published" always means we went looking and found nothing.

What all ten are judged on

Same four questions, asked of everyone, so the comparison means something.

1. Is the price published? Written down, before a sales call. Not "available on request"
2. Is the term published, and does it match the marketing? Two separate questions, and one firm here answers them differently
3. Is there SaaS proof, named and measured? A named client, a number and a date range. Most give you two of the three
4. Does independent review evidence exist, and does it agree with itself? One rating on one platform is weak. Two platforms disagreeing is informative

Nobody scores four out of four, us included.

1. Grow Surely

Best for: SaaS teams that want the market tested before they commit budget.

We're on our own list, so discount accordingly and judge the specifics. Our SaaS proof is SprintFWD: $300,000+ in closed deals, on the record from Kegan Burgess, Head of Sales, with a video interview you can watch. The campaign behind it sent 91,600 emails at a 3.41% reply rate and produced 116 opportunities in three months. Follosoft, field service SaaS, closed $160,000+ in four months at a 4X return, with three clients inside the first 60 days.

Pros. The seven-day pilot is free and runs before any retainer is quoted, so the first thing you see is real replies from your real market. No minimum term at any point. Our reply rate is published per send across 6,074,430 emails, which is the comparable denominator and almost nobody here uses it.

Cons. The $5,000 floor is higher than several firms here, so a seed-stage team testing the water has cheaper options. Email-led, so if your buyers only answer the phone we're the wrong shape. Shared warm infrastructure is what makes a one-day start possible, which also means the sending reputation isn't exclusively yours.

Verdict. Pick us if you want the market tested before money changes hands, and if email is where your buyers actually are. Pick a phone-first firm if they aren't.

2. memoryBlue

Best for: SaaS companies whose buyers genuinely answer the phone.

memoryBlue is a phone company and says so plainly, which is more useful than the firms that claim every channel. Their own site states 85% of booked meetings come directly from the phone, contrasted explicitly with email and LinkedIn.

Pros. 650+ dedicated reps, so capacity is not a constraint. The audition-to-hire option lets you convert a rep onto your own payroll, which is genuinely rare and valuable if you're building a team rather than renting one forever. They also do training and recruitment, so the handover path exists.

Cons. No published price or term. Rented headcount means you manage the reps day to day, so you need a sales leader in place. If your buyers don't pick up the phone, 85% of their engine does nothing for you.

Verdict. Pick memoryBlue if phone works in your market and you eventually want the team in-house. The audition-to-hire route is the strongest argument here and nobody else on this page offers it.

3. SalesRoads

Best for: Teams that want to budget exactly, down to the seat.

SalesRoads publishes its full rate card, which on this page almost nobody manages. You can model the cost before you talk to anyone.

Pros. Fully published pricing that falls to $7,192 per seat at six seats, so volume discounts are transparent rather than negotiated. Each seat includes 500 prospect records a month, a dashboard and CRM integration, so you know what the number covers.

Cons. Billing runs per four-week period, not per month, so a year is 13 invoices rather than 12. That is a real 8% you will not find in the headline. No LinkedIn outreach at any tier, and no published term.

Verdict. Pick SalesRoads if budget certainty matters most and your market answers the phone. Multiply the quoted figure by 13 before you compare it to anyone else's monthly price.

4. Leadium

Best for: SaaS teams that specifically want American reps.

Leadium states a 100% US-based team and month-to-month terms, which is an unusual combination in a category where most firms publish neither.

Pros. Month to month with no minimum, published. US-based team, stated rather than implied, which matters if your buyers can tell and some can. Smaller and more flexible than memoryBlue or SalesRoads.

Cons. No published price. A smaller firm means less bench if someone leaves your account. Proof is thinner than the larger firms here.

Verdict. Pick Leadium if onshore reps and a short leash both matter. Ask what happens to your account if the assigned rep leaves, because at this size that is the real risk.

5. LevelUp Leads

Best for: Teams that want contractual activity volumes.

LevelUp Leads sells packages with stated daily call and email volumes, which is a different purchase from booked meetings and worth understanding before you sign.

Pros. Publishes a price floor, which puts them ahead of most here. Activity volumes are stated contractually, so you know exactly what you're buying and can hold them to it.

Cons. Activity is not an outcome. A contract guaranteeing dials and sends guarantees nothing about meetings. The three-month commitment is prepaid, so you're funding the ramp before you know whether it works.

Verdict. Pick LevelUp Leads if you want volume guarantees and have someone in-house to convert the activity. Pick someone else if you want to be sold outcomes.

6. Callbox

Best for: SaaS selling into APAC, LATAM or EMEA.

Callbox is built for multi-region outbound with native-language callers, which almost nobody else here can do properly.

Pros. Native-language callers across six offices and four continents. If your expansion market crosses languages, this is a genuine capability rather than a claim.

Cons. Case studies are largely anonymised, so you get a result with no name attached. No published price or term. You're paying for geographic reach, which is wasted if your market is one country.

Verdict. Pick Callbox if your target market genuinely spans regions. If it doesn't, you're buying capability you won't use.

7. SalesCaptain

Best for: Teams that want a whole pod rather than a rep.

SalesCaptain assigns a team per account rather than a seat: an account manager, two business development reps, two researchers and a copywriter.

Pros. The pod model means research and copy are staffed rather than squeezed into a rep's day, which is usually where quality dies. Biweekly syncs and Slack access are stated, so the working rhythm is defined up front.

Cons. No pricing page exists. Clutch lists a $5,000+ minimum and a $200 to $300 hourly band, which are third-party figures rather than theirs. No cold calling at any tier, so this is email, LinkedIn and text only.

Verdict. Pick SalesCaptain if you want copy and research properly staffed and your buyers are reachable without the phone. Confirm the price in writing, because the only figures available come from somewhere else.

8. A-Sales

Best for: Teams chasing phone-led meeting volume who will do their own diligence.

A-Sales publishes 32 named case studies, which is more checkable proof than almost anyone here. Their review record is the problem.

Pros. Thirty-two named case studies is a genuinely deep, checkable body of proof. Phone-led with real volume behind it.

Cons. They rate 4.9 on Clutch across 84 reviews and 2.6 on Trustpilot across 83. Near-identical sample sizes, opposite verdicts. That gap is the single most interesting data point on this page and it needs explaining before you sign anything.

No published price or term.

Verdict. Pick A-Sales only after you've read both review sets yourself and asked them directly about the gap. The case studies are real; the ratings disagreement is too.

9. Cleverly

Best for: Seed-stage SaaS testing whether outbound does anything at all.

Cleverly has the lowest entry price here by a wide margin, and a contract detail that matters more than the price.

Pros. Genuinely cheap and genuinely published. Around 4.2 across 84 Clutch reviews, a real sample. The cheapest way to find out whether your market responds to outbound before spending five figures.

Cons. Their cold email page says "Month-to-month, no contracts." Their Terms of Use set a 90-day initial term that auto-renews every 30 days and needs ten days' written notice to cancel. The contract is the one that counts. Light-touch service at this price.

Verdict. Pick Cleverly only after reading the Terms of Use rather than the marketing page. Treat it as a cheap market test, not a sales function.

10. Lead Gen Dept

Best for: Teams wanting a mid-sized partner with a current review record.

Lead Gen Dept is smaller than the top of this page but has recent, readable reviews, which beats a large stale record.

Pros. Reviewers specifically credit them with delivering more meetings than agreed, which is a rarer direction of complaint than the opposite. The sample is thin but current.

Cons. Some reviewers report lead guarantees that weren't met, so pin down exactly what any guarantee covers and what the remedy is. No published price or term, and a much smaller evidence base than memoryBlue or SalesRoads.

Verdict. Pick Lead Gen Dept if you want a mid-sized partner and you'll get the guarantee into the contract rather than the proposal.

The ten, scored against the four standards

Six of the ten publish neither a price nor a term. That is the category's normal state rather than a scandal, but it does mean most of your diligence has to happen on a call where the other side controls the information.

Five questions to ask on the first call

1. "Am I buying meetings or buying seats?" This is the whole decision and the answer changes what underperformance costs you. A seat that books nothing still invoices.
2. "Does your reply rate count auto-replies?" They're 51% of everything that comes back in our data. If the answer is unclear, halve whatever number they quoted.
3. "Send me the terms before the proposal." Then search that document for "initial term", "auto", "notice", "refund" and "cap". One firm here has a 90-day term behind a page that says no contracts.
4. "Is that price monthly, or per period?" One agency on this page bills every four weeks, which is 13 invoices a year. Ask, then multiply before comparing.
5. "Show me a SaaS client with a name, a number and a date range." Most will give you two of the three. The missing one is usually the date, because the result is older than it sounds.

"Outbound sales agency" is four different purchases wearing one phrase

Search that term and you'll get ten firms that look interchangeable. They aren't, and the differences are larger than the price differences.

For a SaaS company the second row is the trap. Rented headcount looks like the cheapest path to a sales function, and it's priced per seat, so your cost scales with heads rather than with results. A seat that books nothing costs exactly what a seat that books twelve does.

That's fine when you have a sales leader who can diagnose why a rep is underperforming. It's expensive when you don't, because you're paying for management capacity you have to supply yourself.

The honest in-house comparison, with sources

Every agency on this page publishes a build-versus-buy calculator, and every one of them is built to produce the same answer. Here's the version with citations attached.

Two things that calculator on the agency's website leaves out. Commission sits inside wages in the BLS data, so the 24.7% applies to total earnings rather than base, which most calculators get backwards in their own favour.

And tooling cost is not independently measured anywhere. Every figure you'll see for it traces back to a vendor. We looked, and there's no survey behind any of them.

The widely circulated "$154,000 in-house SDR" number is published by a company selling outsourced appointment setting, and none of its six line items cites a source. Treat it accordingly.

The CAC payback clock decides this, not the monthly fee

SaaS is the one category where this comparison is actually computable, because you already know your average contract value and roughly how long a customer stays.

So run it in that order. Start with how long you can afford to wait to get the money back, then work out which pricing model survives it.

Here's the arithmetic nobody runs before the call. Across Grow Surely's 6,074,430 emails, one booked meeting takes roughly 2,100 emails for the most responsive audiences and 4,700 for the least.

Convert any quote into that unit. A $12,000 monthly seat and a $5,000 retainer are not comparable numbers until you know how many held meetings each produces, and whether the reply rate behind that estimate counted auto-replies.

Auto-replies are 51% of everything that comes back in our data. A provider quoting a reply rate that includes them is quoting roughly double the real one, and most of them do.

What a SaaS outbound list should be built from

Firmographics alone produce the list your competitors already bought. These are the signals that mean somebody has a reason to answer this month.

• Hiring for the problem you solve. A company posting three roles your product removes the need for is telling you its budget cycle out loud
• A competitor's tool in the stack. Technographic data tells you who already pays for this category, which removes the hardest objection before you write
• A funding round in the last 90 days, because the spending window is short and well documented
• A new VP of the function you serve. New executives buy to show early wins, and they buy fast
• Integration announcements, which tell you what a company is building toward rather than what it bought last year

Ask any agency which of these it can actually build against. If the answer is job title plus company size plus headcount band, you're buying a filtered database and paying agency rates for it.
